Water footprint important but misunderstood indicator
Water footprinting is the future of water conservation
The Water Footprint (WF) of a product, process or person provides an indication of how much fresh water is used, both direct and indirect, to produce a product, drive the process or lead a lifestyle. Although it is a very important indicator it is often misunderstood. Popular media contribute to this misunderstanding as they often use the WF to illustrate the large quantities of water used to produce a product without explaining what the footprint actually means.  

An example is a single kilogram of beef that has an average global WF 15 415 litres. This indeed sounds scary, but when one places it in context, the total WF includes 14 414 litres green water, 550 litres blue water and 451 litres grey water. Green water is the evapotranspiration of precipitation (rain), blue water is the fresh water from dams, rivers and underground sources, while grey water is the amount of fresh water required to dilute polluted water to acceptable levels.

According to Frikkie Maré, a lecturer at the Department of Agricultural Economics at the University of the Free State (UFS), the WF concept provides a new look at water conservation and sustainability. “Although the WF is not an indicator of sustainable water use, it is a useful tool to calculate total water demand and is used in the estimation of sustainability. Traditionally, water conservation was focused on the direct water use of individuals (time taken to shower, leaking taps etc.), but the WF now provides a tool to focus attention on total water demand.”

The Water Footprint Network assists individuals with this new trajectory on the water conservation front with the personal water footprint calculator that allows individuals globally to determine their personal water demand through their direct and indirect water usage. Maré believes this can cause the necessary paradigm shift in the aqua status quo by creating awareness among consumers on their total water demand.

With Water Week underway from 17-23 March 2018, UFS students and staff members are urged to make use of the personal water footprint calculator in order to become aware of the real importance of fresh water in our everyday lives.

UCT scholar in Philosophical Psychology of Black Existence to join Judge Albie Sachs on stage
2015-03-23

Dr Buhle Zuma, listed as one of the 2011 Mail & Guardian 200 Young South Africans, is coming to the Bloemfontein Campus. He will share a stage with civil rights activist and former Constitutional Court, Judge Albie Sachs, on Thursday 26 March 2015 in the Albert Wessels Auditorium at 12:30.

Respondent to Judge Sachs

A former Mandela Rhodes scholar, and currently a young lecturer at the University of Cape Town's Psychology Department, Dr Zuma is particularly interested in issues at the heart of our rainbow nation . His research asks the question: What does it mean to be human for black people after centuries of dehumanisation? Dr Zuma also looks at the role of desire and fantasy in the political imagination of post-apartheid South Africa. He describes his developing thought and work as the Philosophical Psychology of Black Existence.

Dr Zuma will act as respondent to Judge Sachs’ public lecture, ‘Sites of memory, sites of conscience’ [Hannes, please link to the article on the main website]. This lecture will form part of a series that focuses on how the creative arts represent trauma and memory – and how these representations may ultimately pave the way to healing historical wounds.

Vice-Chancellor’s Lecture Series on Trauma, Memory, and Representations of the Past

This lecture will launch of the Vice-Chancellor’s Lecture Series on Trauma, Memory, and Representations of the Past. It forms part of a five-year research project led by Prof Pumla Gobodo-Madikizela [], funded by the Mellon Foundation [].
